[Vibram] Need Help ID'ing a Vibram Prototype

[walker]

I've got a bunch of Vibram prototypes I'm about to put up for sale, here or ebay. Early on I was on the Vibram tester team and got the prototypes. However, there is one with no markings that I'm not 100% sure what it is. My memory is not the best.

I'm fairly certain it is a Trek, but the rim depth (not rim width) is a bit more shallow then the production treks. There are no molded markings, just the weight written in sharpie. Any one else here that received testers that can confirm the Trek proto's were unmarked?

btw, I have all the three original putters, sole, ibex, obex, ascent, lace, 419b, and 420b protos. After that I stopped receiving any. So the trek fits in the timeline also.

trek makes sense

The production model would be the Trak irc. I don't think it ever had the name trek molded in, but I could be wrong.

Well, I have two other ones. The yellow one is definitely production, stamped "Trak". The red one is stamped "Trek", with the flight stamp molded but not marked. (was this perhaps the Tester?). If so that would mean the Green mystery blank one is something else?

Aside from being slightly shallower rim, the green one also has a little bit of a curve to the bevel, where as the other two are flat across the bevel.
